Technical Field

[0001] The utility model relates to the technical field of textile fabrics, in particular to a tear-resistant, wear-resistant and flame-retardant polyester fabric. Background Art

[0002] With the development of science and technology and the improvement of people's living standards, textiles have evolved from traditional clothing to industrial and decorative uses. Traditional textile materials and structures can no longer meet people's high-quality requirements. At present, people pay more attention to the research of textiles with protective functions, especially textiles with flame retardant functions. When encountering a fire, textiles with flame retardant functions can effectively prevent the spread of fire, thereby reducing the losses caused by the fire.

[0003] However, the common polyester fabrics on the market usually do not have flame retardant properties. After long-term use, the tear resistance and wear resistance will deteriorate, affecting the service life of the polyester fabric. In order to meet people's needs, it is necessary to develop a tear-resistant, wear-resistant, flame-retardant polyester fabric. Utility Model Content

[0012] In the figure: 1-warp yarn, 2-weft yarn, 3-binding yarn. DETAILED DESCRIPTION

[0013] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] Combination Figure 1 The present embodiment is described in detail. A tear-resistant, wear-resistant and flame-retardant polyester cloth comprises: a fabric body; the fabric body is an orthogonal weave fabric; the orthogonal weave fabric is formed by three groups of yarns, namely, warp yarn 1, weft yarn 2 and binding yarn 3, which are interwoven perpendicularly to each other; the warp yarn 1 comprises a first warp yarn and a second warp yarn, the first warp yarn is a flame-retardant polyester filament, and the second warp yarn is formed by twisting aramid 1313 fiber filament and ultra-high molecular weight polyethylene fiber filament; the binding yarn 3 is formed by twisting flame-retardant acrylic phenolic resin fiber yarn and ultra-high molecular weight polyethylene fiber filament.

[0015] Flame-retardant polyester filaments are generally made by adding phosphorus-containing compounds or halogen-antimony composite flame retardants to the spinning melt, and then melt spinning and stretching. They have excellent flame retardancy and only melt without burning when exposed to fire. Ultra-high molecular weight polyethylene fiber is the strongest chemical fiber with good chemical stability and excellent wear resistance, impact resistance, and cut resistance. The most prominent feature of aramid 1313 fiber is its high temperature resistance and limiting oxygen index greater than 28%. It is a flame-retardant fiber that will not burn in the air, does not support combustion, and has self-extinguishing properties.

[0016] Specifically, the flame-retardant acrylic phenolic resin fiber yarn is a 40:60 blended yarn of phenolic resin fiber and flame-retardant acrylic. Phenolic resin fiber is a polymer compound made from thermoplastic phenolic resin and cross-linking agent through melt spinning and thermosetting process. Because it has benzene ring as the skeleton, the three-way cross-linked molecular structure can ensure its excellent thermal stability. It only carbonizes at high temperature without melting and shrinking. It has excellent flame retardancy, corrosion resistance, ablation resistance and thermal insulation. Flame-retardant acrylic is modified acrylic using ultraviolet grafting technology, sol-gel process, etc. It has flame retardant properties, increased breaking strength, increased curling, increased entanglement between fibers during spinning, and increased cohesion.

[0017] The orthogonal weave fabric is a three-dimensional fabric with binding yarns 3 interwoven in the thickness direction, which significantly improves the tear resistance, bursting force and other properties of the fabric in the thickness direction, and has the advantages of high specific strength, high specific modulus, good impact resistance and the like.

[0018] Furthermore, the orthogonal weave fabric adopts an overall orthogonal form. The form of bundling all the warp yarns 1 and weft yarns 2 together is overall orthogonal. In one interweaving process, the bundling yarn 3 at the top of the warp yarn 1 is transferred to the bottom of the warp yarn 1, and the bundling yarn 3 at the bottom of the warp yarn 1 is transferred to the top of the warp yarn 1, and the next interweaving process repeats the same work. The bundling yarn 3 bundles the warp yarn layer and the weft yarn layer fed in the weaving process into a multi-layer three-dimensional fabric according to the interweaving rule of the woven fabric. The weft yarn 2 must have one more layer than the warp yarn 1 to complete the bundling task.

[0019] Furthermore, the warp yarns 1 are arranged in the order of one first warp yarn and one second warp yarn.

[0020] Furthermore, the weft yarn 2 is twisted by aramid 1414 fiber filament and high-strength low-strength polyester industrial yarn. Aramid 1414 fiber filament has extremely high tensile strength and excellent heat resistance and toughness, and also has good resistance to strong alkali, organic solvents and bleaching, as well as resistance to insect infestation and mildew. High-strength low-strength polyester industrial yarn has good mechanical properties, with a breaking strength of 8.55 cN / dtex and an elongation at break of 12.7%. Compared with ordinary polyester, it has higher breaking strength and lower elongation at break, and has a higher initial modulus and better creep resistance.

[0021] Furthermore, the weight of the fabric body is 450-550g / ㎡. Under the same raw material conditions, the thickness of the fabric increases, the tear resistance and wear resistance of the textile are better, which is conducive to extending the service life of the polyester fabric.

[0022] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
